A water pump is used if necessary to pump large volumes of water or create a pressure when it is supplied. The device has several types and is used in various fields, for example, in construction and agriculture, in suburban areas and in public utilities, in industry and fire fighting.
According to the field of application, such a mechanism as a water pump is divided into domestic and industrial.
The household pump is used to move the water flow or create a water pressure in the water supply of country houses, when draining basements, to change the water in the pool, watering the garden. An increase in pressure is necessary to supply water to multi-storey buildings, for the normal operation of household units (washing and dishwashers). A distinctive feature of a household pump is the need for clean water and its relatively low productivity, which is enough to meet the needs of a private household.
The industrial pump for pumping water is characterized by enhanced technical characteristics. It is used to work with water of varying degrees of pollution. Often the pump is used to work with other liquids, for example, pumps are released for pumping chemically active substances, oil products and fecal matter.
Water pumps are classified according to purpose, thus distinguishing between:
1. Submersible pumps:
· Downhole;
Drainage
Fecal;
· Well.
2. Surface pumps:
Circulating
Pressure
· Pumping stations;
· Universal water pump for summer cottage.
Submersible pumps
This group of pumps was named due to the fact that their operation is possible only when the unit is immersed in water at different depths.
Well pumps typically have a cylindrical elongated casing shape. A small diameter facilitates the process of absorbing water from a sufficiently large (more than 20 m) depth. This greatly expands the scope of the pump and makes it possible to operate it in narrow wells. Pumps of this type are characterized by high power.
Well pumps are used to lift lightly contaminated water from wells. With high performance, such pumps are characterized by relatively low noise, which makes it possible to use them to supply water in cottages or in cottages.
Drainage pumps pump out contaminated water saturated with silt and sand, other substances, particles of which do not exceed 30 mm in diameter, from pits and pits, trenches and basements.
Fecal pumps are used for pumping heavily contaminated waters, in which various impurities and long-fiber inclusions are present. The normal functioning of the unit is ensured by the presence of a special cutting device in the pump mechanism.
Water pump: surface pumps
This category of pumps does not require immersion in water, they are installed near ponds, while the water is drawn using a special hose. A water pump of this type provides the rise of water from wells and wells for irrigation of plantations, to drain the basement, for summer cottage water supply, to ensure normal water supply during fire fighting.
A feature of surface pumps is their ability to pump water only from shallow depths, and therefore they are used in places of convenient access to water. The surface-mounted water pump has small dimensions, it is very easy to use, it is characterized by compactness and mobility.
Garden pumps (pomps for summer cottages) are used for watering plots, it is convenient to pump water from the pools with them.
Pressure pumps are used to increase the pressure in the system.
Pumping stations have an additional water tank, they are produced with a special control unit. They have a particularly high power and increased operational resource.
